10. Make Sense and Persevere The flag of the

kumpel [21]

Answer:

$s=\frac{P}{3}$
Dimensions of the flag:

$lenght=6.65\ ft\\\\width=3.5\ ft$

Area of the flag: $23.275\ ft^2$

Step-by-step explanation:

The missing figure of the exercise is attached.

We know that the perimeter of the triangle is given by:

$P= 3s$

Where "s" is the side lenght of the triangle.

Solving for "s", we get:

$s=\frac{P}{3}$

Therefore, if the perimeter of the triangle is 126 inches, its side length is:

$s=\frac{126\ in}{3}\\\\s=42\ in$

Since $1\ ft=12\ in$ , we know that "s" in feet is:

$s=(42\ in)(\frac{1\ ft}{12\ in})=3.5\ ft$

The area of a rectangle can be calculated with this formula:

$A=lw$

Where "l" is the lenght and "w" is the width

We can observe in the figure that the lenght and the width of the flag are:

$l=1.9s\\w=s$

Then, the dimensions of the flag are:

$l=1.9(3.5\ ft)=6.65\ ft\\w=3.5\ ft$

And the area is:

$A=(6.65\ ft)(3.5\ ft)=23.275\ ft^2$

The ratio of two numbers is $2:3$. when 6 is subtracted from the smaller of the two numbers and 7 is added to the larger of the

patriot [66]

Answer:

Step-by-step explanation:

Let the smaller and larger numbers be represented by S and L, respectively.

S/L = 2/3 . . . . the original ratio of the numbers

3S = 2L . . . . . multiply by 3L

(S-6)/(L+7) = 2/7 . . . . the new ratio of the numbers

7(S-6) = 2(L+7) . . . . . multiply by 7(L+7)

7S -42 = 2L +14

Using the expression for 2L from the first ratio, we can substitute to get ...

7S -42 = 3S +14 . . . . substitute 3S for 2L

4S = 56 . . . . . . . . . . .add 42-3S

S = 14 . . . . . . . . . . . . . divide by 4

The original smaller number was 14.
